[0002]

2. Description of the Related Art Referring to FIG. 6 which shows a conventional optical disk apparatus 41 of this type in a perspective view, FIG. 2 which shows a perspective view of an exposed medium 6, and FIG. The optical disk device 41 includes a tray 42 on which the exposed medium 6 or the cartridge storage medium 3 is placed and performs a load / unload operation, a motor 48 for driving the load / unload of the tray 42, and an unload operation of the tray 42. And an eject switch 45 to be operated.

FIGS. 7 (a) to 7 (d) show the operation when loading the exposure medium 6 or the cartridge storage medium 3 into the conventional optical disk apparatus 41 having such a configuration.
This will be described with reference to FIG.

FIG. 7A shows a state where the tray 42 is pulled into the optical disk device 41.

At this time, the tray detecting sensor 47 is in the ON state, but the exposed medium 6 or the cartridge storage medium 3 is not mounted on the tray 42. When the eject switch 45 is pressed in this state, the optical disk device 4
1 drives the motor 48 to start the unloading operation of the tray 42. Continue the unloading operation of the tray 42,
When the tray detection sensor 47 is turned off, the optical disk device 41 stops the rotation of the motor 48, and the optical disk device 41 stops driving as shown in FIG.
The state shown in FIG.

[0006] Next, as shown in FIG.
2 is loaded with the cartridge storage medium 3.

After the cartridge storage medium 3 is loaded in the tray 42, the optical disk device 41 pushes the front side of the tray 42 toward the optical disk device 41 to turn on the tray detection sensor 47 as shown in FIG. Or, when it is detected that the eject switch 45 is turned on, the motor 48 is driven to rotate, and the tray 42 is started to be pulled in.
After operating to the predetermined position, the loading operation ends.

Therefore, in the conventional optical disk device 41, when loading the exposed medium 6 or the cartridge storage medium 3, the eject switch 45 is pressed to unload the tray 42, and then the exposed medium 6 or the cartridge storage medium 3 is loaded. It is necessary to place the medium 3 on the tray 42 and further press the eject switch 45 or the tray 42 to pull out the tray 42 to perform three operations.

[0009]

As described above, in the conventional optical disk apparatus, when loading an exposed medium or a cartridge storage medium, an operation of pressing an eject switch to unload a tray, an exposed medium, or a cartridge. There is a problem that an operation of placing a storage medium on a tray and an operation of pressing an eject switch to pull in the tray or an operation of pressing the tray are required.

It is an object of the present invention to provide an optical disk device in which the operability of a user when loading an exposure medium or a cartridge storage medium is improved.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic perspective view showing a first embodiment of the optical disk apparatus of the present invention.

Referring to FIG. 1, an optical disk apparatus 1 according to the present invention is an optical disk apparatus 1 that can use both a cartridge storage medium 3 and an exposed medium 6 not stored in a cartridge. The tray 2 on which the tray 6 is placed and which can be freely loaded and unloaded into the opening 9 of the housing, a motor 8 for driving the loading and unloading of the tray 2, and an eject switch for unloading the tray 2 5, and a non-contact optical cartridge detection sensor 4 provided on the tray 2 on which the cartridge storage medium 3 or the exposure medium 6 is placed.

Next, the operation when loading the exposure medium 6 or the cartridge storage medium 3 into the optical disc apparatus 1 of the present invention shown in FIG. 1 will be described with reference to FIGS. 4 (a) to 4 (d). I do.

FIG. 4A shows that the tray 2 is the optical disk device 1
It is in the state pulled in. At this time, the tray detection sensor 7 is in the ON state, but the exposed medium 6 or the cartridge storage medium 3 is not mounted on the tray 2. When the eject switch 5 is pressed in this state,
The optical disk device 1 drives the motor 8 to start the unloading operation of the tray 2. When the unloading operation of the tray 2 is continued and the tray detection sensor 7 is turned off, the optical disk device 1 stops the rotation drive of the motor 8 and
The state shown in FIG.

Next, as shown in FIG.
Is loaded with the cartridge storage medium 3.

When the cartridge storage medium 3 is placed on the tray 2, the cartridge detection sensor 4 detects the presence of the cartridge storage medium 3 and turns on as shown in FIG. Usually, the cartridge storage medium 3 is placed from the front of the cartridge storage medium 3 when the cartridge storage medium 3 is mounted.
Are arranged on the tray front side F from the center of the tray 2. When the ON state of the cartridge detection sensor 4 is detected, the optical disk device 1 automatically starts to draw the tray 2 after a certain period of time, moves the tray 2 to a predetermined position, and ends the loading operation.

In the above embodiment, the operation when loading the cartridge storage medium 3 into the optical disk device 1 has been described, but the operation when loading the exposure medium 6 into the optical disk device 1 is the same.

That is, the location detected by the non-contact optical cartridge detection sensor 4 is the cartridge storage medium 3
In the case of (1), the presence or absence of the cartridge case is detected, whereas in the case of the exposed medium 6, the only difference is that the presence or absence of the medium surface is detected.

Next, a second embodiment of the optical disk device 21 of the present invention is shown in FIG.

The second embodiment showing the operation when loading the exposure medium 6 or the cartridge storage medium 3 into the optical disk device 21 of the present invention shown in FIG. 5 and the first embodiment shown in FIG. In the second embodiment shown in FIG. 5, a contact type mechanical cartridge detection sensor 24 is provided on the tray 2.

Accordingly, the operation when loading the cartridge storage medium 3 into the optical disk device 21 differs depending on whether the method of detecting the presence or absence of the cartridge on the tray 2 is a contact type, a mechanical type, a non-contact type, or an optical type. And the same as in the first embodiment described above, and a detailed description thereof will be omitted.

The second embodiment of the optical disk device 21 of the present invention has an advantageous effect on the optical disk device 21 using the cartridge storage medium 3.
